Genesis 21:1-13

1The Lord came to help Sarah and did for her what he had promised.

2So she became pregnant, and at the exact time God had promised, she gave birth to a son for Abraham in his old age.

3Abraham named his newborn son Isaac.

4When Isaac was eight days old, Abraham circumcised him as God had commanded.

5Abraham was 100 years old when his son Isaac was born.

6Sarah said, “God has brought me laughter, and everyone who hears about this will laugh with me.

7Who would have predicted to Abraham that Sarah would nurse children? Yet, I have given him a son in his old age.”

8The child grew and was weaned. On the day Isaac was weaned, Abraham held a big feast.

9Sarah saw that Abraham’s son by Hagar the Egyptian was laughing at Isaac.

10She said to Abraham, “Get rid of this slave and her son, because this slave’s son must never share the inheritance with my son Isaac.”

11Abraham was upset by this because of his son Ishmael.

12But God said to Abraham, “Don’t be upset about the boy and your slave. Listen to what Sarah says because through Isaac your descendants will carry on your name.

13Besides, I will make the slave’s son into a nation also, because he is your child.”
